When to use
Prognosis and management discussions in COPD.
How it works
Points for BMI, airflow Obstruction (FEV₁% predicted), Dyspnoea (mMRC) and Exercise (6-minute walk). Total 0–10; higher predicts worse survival.
Key points
- Predicts mortality better than FEV₁ alone.
- Can inform rehabilitation and transplant referral.
- Reassess after interventions.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| BMI | > 21 (0) |
|---|---|
| FEV₁ (% predicted) | ≥ 65% (0) |
| mMRC dyspnoea | 0–1 (0) |
| 6-minute walk distance | ≥ 350 m (0) |
→BODE0/10
- 4-year survival (approx.)：~80% 4-year survival
| BMI | ≤ 21 (1) |
|---|---|
| FEV₁ (% predicted) | ≤ 35% (3) |
| mMRC dyspnoea | 4 (3) |
| 6-minute walk distance | ≤ 149 m (3) |
→BODE10/10
- 4-year survival (approx.)：~18%

- Inputs: BMI > 21 (0), FEV₁ (% predicted) ≥ 65% (0), mMRC dyspnoea 0–1 (0), 6-minute walk distance ≥ 350 m (0) → Result: BODE 0 /10（4-year survival (approx.): ~80% 4-year survival） Inputs: BMI ≤ 21 (1), FEV₁ (% predicted) ≤ 35% (3), mMRC dyspnoea 4 (3), 6-minute walk distance ≤ 149 m (3) → Result: BODE 10 /10（4-year survival (approx.): ~18%）
